2008-7-29 · AD-Frustum is a hierarchical representation of the subdivision of a frustum. We augment a 4-sided frustum with a quadtree structure to keep track of its subdivision and maintain the correct depth informa-tion, as shown in Fig. 2. Each leaf node of the quadtree represents the finest level sub-frustum that is used for volumetric tracing. An inter-

2022-4-12 · Keywords: shadows, irregular z-buffer, frustum tracing 1 Introduction While conceptually simple, real-time rendering of hard shadows re-mains an enormous challenge. Most modern applications use vari-ants of shadow mapping [Williams 1978]. But due to discretiza-tion and sampling mismatches between eye- and light-space, robust e-mail:chris.wyman ...
AD-Frustum: Adaptive Frustum Tracing for Interactive …
https://ieeexplore.ieee.org/document/4658194/
2008-10-24 · We present an interactive algorithm to compute sound propagation paths for transmission, specular reflection and edge diffraction in complex scenes. Our formulation uses an adaptive frustum representation that is automatically sub-divided to accurately compute intersections with the scene primitives. We describe a simple and fast algorithm to …
